Transcript SafetyonCall Types of Bloodborne Pathogens

BLOODBORNE PATHOGENS
SafetyonCall
WHAT ARE BLOODBORNE PATHOGENS
• Bloodborne pathogens are microorganisms such as viruses or
bacteria that are carried in blood and can cause disease in
people.
SafetyonCall
TYPES OF BLOODBORNE PATHOGENS
• Bloodborne Pathogens Include:
– Malaria
– Syphilis
– Brucellosis
– Hepatitis B (HBV)
– Human Immunodeficiency Virus (HIV)
SafetyonCall
HEPATITIS B (HBV)
• Is a virus that causes infection and inflammation of the liver.
• Is transmitted primarily through "blood to blood" contact.
• Can lead to serious conditions such as cirrhosis & liver cancer.
• Can survive in dried blood for up to seven days.
• There is no "cure" or specific treatment for HBV.
• Many people develop antibodies to fight the disease which
may prevent future infection.
SafetyonCall
HBV SYMPTOMS
•
Mild flu-like symptoms
•
Fatigue
•
Possible stomach pain
•
Loss of appetite
•
Nausea
•
Jaundice
•
Darkened urine
SafetyonCall
HEPATITIS B VACCINATIONS
• Employees who have routine exposure to bloodborne
pathogens (such as doctors, nurses, first aid responders, etc)
shall be offered the Hepatitis B vaccine series at no cost to
themselves unless:
– They have previously received the vaccine series.
– Antibody testing has revealed they are immune.
– The vaccine is contraindicated for medical reasons.
– In these cases they need not be offered the series.
SafetyonCall
VACCINATION PROCESS
• Series of three shots.
• Second shot is given one month after the first.
• Third shot follows five months after the second.
• This series gradually builds up the body's immunity to the
Hepatitis B virus.
SafetyonCall
HUMAN IMMUNODEFICIENCY VIRUS (HIV)
• AIDS, or acquired immune deficiency syndrome, is caused by
a virus called the human immunodeficiency virus, or HIV.
• It may be many years before AIDS actually develops.
• HIV attacks the body's immune system, weakening it so that it
cannot fight other deadly diseases. AIDS is a fatal disease,
and while treatment for it is improving, there is no known
cure.
SafetyonCall
HIV AND DIRECT CONTACT
• The HIV virus is very fragile and will not survive very long
outside of the human body. It is primarily of concern to
employees providing first aid or medical care in situations
involving fresh blood or other potentially infectious materials.
SafetyonCall
HIV SYMPTOMS
•
Symptoms of HIV infection can vary, but often include:
– Weakness
– Fever
– Sore throat
– Nausea
– Headaches
– Diarrhea
– White coating on the tongue
– Weight loss
– Swollen lymph glands
SafetyonCall
BLOODBORNE PATHOGEN TRANSMISSION
•
Bloodborne pathogens are transmitted through contact with
infected human blood and other body fluids such as:
– Semen
– Vaginal secretions
– Cerebrospinal fluid
– Synovial fluid
– Pleural fluid
– Peritoneal fluid
– Amniotic fluid
– Saliva
SafetyonCall
SKIN PROVIDES A BARRIER
•
Unbroken skin forms an impervious barrier against bloodborne
pathogens. However, infected blood can enter your system
through:
– Open sores
– Cuts
– Abrasions
– Acne
– Any sort of damaged or broken skin such as sunburn or
blisters
SafetyonCall
MUCOUS MEMBRANES
• Bloodborne pathogens may also be transmitted through the
mucous membranes of the
– Eyes
– Nose
– Mouth
SafetyonCall
SIGNS & LABELS
• Warning labels must be placed on containers of regulated
waste, refrigerators and freezers containing blood or other
potentially infectious material; and other containers used to
store, transport, or ship blood or other potentially infectious
materials.
SafetyonCall
WHAT IS REGULATED WASTE
•
Any liquid or semi-liquid blood or other potentially infectious
materials.
•
Contaminated items that would release blood or other
potentially infectious materials in a liquid or semi-liquid state
if compressed.
•
Items that are caked with dried blood or other potentially
infectious materials.
SafetyonCall
EMERGENCIES
• In an emergency situation, always use Universal Precautions:
– Minimize your exposure by wearing
– Gloves
– Splash goggles
– Pocket mouth-to-mouth resuscitation masks
– Other barrier devices
SafetyonCall
IF YOU ARE EXPOSED
• Wash the exposed area thoroughly with soap and running
water.
• Use non-abrasive, antibacterial soap.
• Flush mouth, nose, eyes for 15 minutes if blood is splashed in
mucous membranes.
• Report the exposure to your supervisor.
• Fill out an exposure report form.
• Request blood testing & Hepatits B vaccination.
SafetyonCall
PROTECTION
SafetyonCall
PERSONAL PROTECTIVE EQUIPMENT
• The best protection against exposure is to ensure you are
wearing the appropriate personal protective equipment (PPE).
To protect yourself, it is essential to have a barrier between
you and the potentially infectious material.
SafetyonCall
RULES TO FOLLOW
• Treat all blood or potentially infectious body fluids as if they
are contaminated.
• Always wear personal protective equipment (PPE) in exposure
situations.
• Replace PPE that is torn or punctured.
• Replace PPE that is torn or punctured.
• Remove PPE before leaving the work area.
• Properly disinfect or dispose of used PPE.
• Wash hands immediately after removing PPE.
SafetyonCall
GLOVES
• Gloves should be made of latex, nitril, rubber, or other water
impervious materials.
• Inspect gloves before use.
• Double gloving can provide an additional layer of protection.
• If you have cuts or sores on your hands, you should cover
these with a bandage or similar protection as an additional
precaution before donning your gloves.
• Don’t touch the outside of used gloves.
SafetyonCall
GOGGLES, FACE SHIELDS & APRONS
• Use goggles if there is a risk of splashing or vaporization of
contaminated fluids.
• Face shields provide additional face protection for the nose
and mouth.
• Aprons protect.
SafetyonCall
CONTAMINATED CLOTHING
• Remove clothing that is contaminated with blood as soon as
possible.
• Use Universal Precautions when handling contaminated
laundry.
• Place clothing in approved & labeled bags or containers.
SafetyonCall
HAND WASHING
• Hand washing is one of the most important (and easiest)
practices used to prevent transmission of bloodborne
pathogens.
• Wash hands or other exposed skin thoroughly as soon as
possible following an exposure incident.
• Use antibacterial soap.
• Don’t use harsh, abrasive soaps.
SafetyonCall
HYGIENE RULES
• If you are working in an area where there is reasonable
likelihood of exposure, you should never:
– Eat
– Drink
– Smoke
– Apply cosmetics
– Handle contact lenses
SafetyonCall
FOOD RULES
• Do not keep food or drink refrigerators, freezers, shelves,
cabinets, or on counter tops where blood or potentially
infectious materials are present.
SafetyonCall
DECONTAMINATION & STERILIZATION
•
All surfaces, tools, equipment and other objects that come in contact
with blood or potentially infectious materials must be
decontaminated and sterilized as soon as possible. Equipment and
tools must be cleaned and decontaminated before servicing or being
put back to use.
•
Solution of 5.25% sodium hypochlorite (household bleach) diluted
between 1:10 and 1:100 with water. The standard recommendation
is to use at least a quarter cup of bleach per one gallon of water.
•
Use Lysol or some other EPA-registered tuberculocidal disinfectant.
Check the label of all disinfectants to make sure they meet this
requirement.
SafetyonCall
SPILL CLEANUP
• Carefully cover the spill with paper towels or rags.
• Gently pour 10% solution of bleach over the towels or rags.
• Let sit for 10 minutes.
• Wear gloves to collect & dispose of waste.
SafetyonCall
PRECAUTIONS WITH NEEDLES
• Recap needles only with a mechanical device.
• Use forceps, pliers, or broom and dust pan to move needles.
• Never break or shear needles.
• Needles must be disposed in labeled sharps containers.
SafetyonCall
BROKEN GLASSWARE
• Broken glassware should be sterilized with an approved
disinfectant solution before it is disturbed or cleaned up.
• Glassware that has been decontaminated may be disposed of
in an appropriate sharps container.
• Don’t pick up broken glassware with your hands.
SafetyonCall
